RADIATOR.

Toall whom it may concernf Be it known that I,K1NnEnMAN M. BOB- LETT, a citizen of the United States, residing Y at Dayton, in thecounty of Montgomery and 5 Stateof Ohio, have invented certain new and useful Improvements inRadiators, of which the following is a specification.

-. My invention relates to condensers or fluid V cooling apparatus and more particularly to l0'radiators for cooling the water'which has been circulated about the cylinder of an explosive engine, and is especially adapted for use in automobile construction. The invention however is notlimited to such use, but

may be employed as acondenser in connec-' tion with steam engines, or in connection with refrigerating apparatus for cooling the refrigerating media, or under certain conditions it may be employed as a radiator for heating purposes. I

The object of the invention is to greatly simplify the structure as well as the means and mode of operation of such devices whereby they will not only be cheapened in construction, but will be more eflicient and economical inoperation and unlikely to get out of repair.

A further object is to provide an improved form of conduit which will present to the atmosphere a maximum amount of radiating surface, andwhich will readily permit the expansion. and contraction of the conduit, due to varying thermal conditions, without subjecting the-device to undue strain.

Afurther objectis to'provide a radiator made up of a plurality of separate identical units'n' hich may be assembled to form radiators ofvarious. sizes or proportions.

.YVith thejabove primary and o'ther incidental. objects: in view as will more fully appear in the specification, the invention consists of the features of construction, the parts and *conibination's thereof, and the mode of. a:espeiatiomvortheir.equivalents, as' hereinaf these? folds .or plaits is spread or opened intermediate its ends forming blind'passage's' I tcrxlescribedand'set forth in'the claims.

Referring to the drawings, Figure 1 is a front "elevatlouof the assembled radiator. .1 Figs. 2 and 3-aredeta1l perspective views of .1 ,thetwo members'orhalf units which are unitedwto'form assingle unit, showing the.

Fig. 9 is an enlarged 360 front elevation of a small portion of the assembled radiator. Fig. 10 is perspective view of a modified form of the radiator unit. Fig. 11 is an enlarged transverse sectional view of the radiator unit.

Like parts are indicated by similar characters of reference throughout the. several views. The radiator forming the subject matter hereof is ofthe cellular type, presenting a front surface of pleasing appearance divided into a multitude of geometrical figures of equal shape and proportion; which at the presenttime is a popular style. The radiator comprises essentially a frame hav mg in the upper portion a receiving chain ber 1, and a dispensing chamber 2 'in' the lower portion, connected with the receiving chamber by aplurality of conduits through whichthe water passes from the chamber 1" to the chamber2. These conduits may be either continuous from one chamber'to the other, or may be of short length and ar-' ranged in tiers separatedby intervening water spaces or auxiliary chambers 3' as shown in 'Fig. 1. The conduits are formed by arranging. a plurality of similar units side by side the units being 'so shaped that an intervening water space will be formed intermediate the succeeding units. The units which are all identical in size and construction comprise two parts or members 4 and 5 shown in Figs. 2 and l and Figs. 3 and 5 respectively. Each of the unit parts 4: and 5 are made from a single piece of material. The unitpart a is formed from a strip of material folded at regular intervals to form a series. of reverse bends or plaits-6 project? ing laterally at rightangles from the-general plane or web ofthe member. Each-of or .cuZs-rZe-sac 7;: The opposite edges of these folds 'are compressed to parallelism and united as shown in the drawings. .-The opposite edges .of'the exterior surface'of the member areofis'et or flanged as indicated at 8: The "folds or seams are opened only between such offset or flanged portions, butthroughout suchoffsetportion the folds are closed. The terminal fold of the member- 4 folded again upon itself to parallelisxmg forming a fold of triple thickness as at.9, in which the edge of the opposite member is engaged to form a uniting seam. The other unit part is stamped for a single sheet of material, the opposite ends of whichare bent at right angles to themain plane thereof, as shown at 10. The opposite edges of the member are offset or flanged as at 11 in a manner corresponding to the offset or flange S of the member 4. Intermediate the ofiset portions 11 of the memher 5 arev preferably, though not necessarily one or more longitudinal beads 12 projecting above the-general surface of the member. The unit parts 4 and 5 are united by introducing the projectingedge 10 of the member 5 within the terminal fold 9 of the member 4, the edges of the folds or seams ,6 being brought into contact with the interior surface of the member 5, as shown particularly in Fig. 6, thereby forming a plurality of rectangular air passages 13 separated by the blind water spaces or cuZs-cZc-sac 7 which communicate with the vertical water conduit as hereafter described.

Inconstructing the radiator, a plurality of the units formed as described are placed side by side, as shown in Figs. 7 and 8, with the side 5 of one unit adjacent to the side 4 of the next succeeding unit. The

offset. or flanged portions 8 and 11 of adjacent units contact each other, separating the adacent' sides 4: and 5 of succeeding units, forming vertical water spaces or conduits 1 4, as. shown in Figs. 7 and 8. The longi-- ,tudinal ribs or beads 12 form spacers within the conduits, preventing the collapse of the conduit through expansion-of the material or through undue pressure or accident. There is thus formed a vertical water space or conduit between the succeeding units as shown'in Fig. 7, with which the blind pas.

sages or o'uls-dc-s'ac .7 communicate, and of which they form lateral extensions. By referring to said figure, it will be seen that the radiator is made up of separate and independent passages 14: between each vertical series of air spaces 13, having lateral ramifications7 extending above and below each air space 13. Thuseach air space 13 is inclosed 011 all four sides by a waterspace, the vertical conduits connecting the radiator chambers bounding the air space 13 on oppositesides, and the blind passages 7 communicating with one of said eondults bounding each air space above and below. By this construction every portion of the structure exposed to the atmosphere becomes a radiating surface. Each vertical condrutl w th its lateral ramificationsis separate and 111- dependent of every other conduit and its ramifications. Likewise each vertical series of air spaces, that'is the air spaces of. each unit, are separate and independent of each other vertical series of air spaces or unit, but

the air spaces of each series are intercommumcatl'ng through the interior of the beads 12, as is shown in Flg. 7. After a plurality of the units have been assembled they are. united into one structure by soldering or by dipping which unites the offset portions 8 and 11. of succeeding units and closes the eX- tremities of the folds or plaits 6.,

The warm water discharged into the upperchamber 1 passes downward through the several conduits 14, and their ramifications 7 in a thin film or stratum, and is discharged into the lower chamber 2. By the. series of ramifications 7 the passage is made of maximum length and the wallofsuch passage is exposed throughout to the atmosphere.

In Fig. 10 is shown a modification of the radiator unit formed by uniting two identical members similar to the member 4 except that the folds or plaits 6 are located at as before described, except that the blind directions from the conduit,

From the above description it will be apparent that there is thus produced a device of the character described, possessing passages or cuZs-de-sac-will extend in both the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportion, detail construction, and arrangement of parts Without departing from the principle involved or sacrificing.

any of its advantages.
